Question

earth is not a perfect circle. due to the ______ gravitational pull, earth bulges out on the sides closest to and farthest from the moon. this distorting pull is known as a tidal force, and it is responsible for the changes in water levels that are called high and low tides. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a moons b moons c moons

Explanation:
